Hi ,
Please take a look around the website. A link that may help
https://bpdfamily.com/message_board/index.php?topic=206132Communicating with a BPD is a minefield; also everything doesn't work for everyone. Validating is tricky and can come across as condescending , but it's worth a try. It also takes lots of trial and error. In my particular case, validation did work for me a little at the beginning, but once my adult son got more dysregulated, it didn't work.
Also it helps to try not to take what she says personally. ( Very hard, I know). If you can, can you give a specific example, maybe we can brainstorm it.
You are not alone.
